In those, classes or inkling nnichines in which type carriers are moved in one directioirhy springs to extents determined by the ghe'ys depressed, it is necessary to employ ,"spri ngs of suchlstrcnglh as will insurethenecessury rap d action, and in quick acting machines, as those driven lay motors, these v ,tipi'iiigs musthe correspondinpl) heavier.

W tile my invention may he empio'yed in connection with machines of .rhfilerent con structions', I have illustrated it in connection [with the parts .of such a machine as is shown in Letters Patent No. 763,692, granted to me June 28, 1-904. As in said machine, there I, 1 ore t pe carriers 4.03 which, as shown, are in the ti;

rm of levers, and with each-carrier is connected a rack strip 404, and springs 1494 connected with these rack st rips tend tic carry the parts so as to hringstops 6130 upon the stri' s against the stems of such keys 201 as may edepressed the ex tent. of movement Specification of Letters Patent.

depending upon the key depressed, and a corrcspomling type of each typelcver being thcrelrv brought over the platen 880 into printingv ositlon. With the type carriers is combiner u suitabledevicefor shifting the some to normal position prior to each n'int. ing operation. Asshown, the said rleviee consists of e plate 401 constituting part of tr swinging frame J, which, whencarrieul toward and with the type carriers, will set them till to normal position. As onemeansof 0pcreating the device or-jramc J, there is shown Patented'May 25; 19cc;

a com 900, and a roller bearing)? of the frame is held in contact with the cam-in one direction by the action of-tlle springs 404, in

the construction shown, so that as thecsm is lifted to its upper position, the snidsprings will carry the levers to the printing positions determined by'the extentoi movemcnt perlevers however rapidly the machine nifty be operated.

Instead of depending upon the springs 40% alone to hold thetype currielsagaiinst the operating device 4G1 or, whatever it may he,

'1 connect. the operating device and crich type, lever by a spring connection, as tor instance,

by a, spring a, so arranged that it tends to hold the levers and the o wreting device in close connection, and in the nhsence of any int-erlcrencc, the two will swing together u.n

dcr the nctionof the cam or, other upcoming" part. When the frame J is swun luickwerd, as the cum descends in carrying t retype curricrs to normal position, only the springs 404" are pvtnmlcr stress, hut when the corn is raised the l'ruine',-l w ll swing toward the cum and all of the type carriers cnpnhleof movement \\'1ll$\\'lllf 1 ifii'wtllll will the ironic, unless the pa rts :5 re operated with such 1'ap1,d

ity that the frame is swuzignwcg' from these levers, in which case the springs aw'iil be extended or put under stress so that notion of the two a wings is thrown upon each lever to o crate the some and insure its ts siredra it mrwemcnj in other words, the:

stress 0 both the springs rec one 4 git-eyes the ()liiiil adding w quired to insure-the desired rapid action, after the ofi'leration of themachine begins in printing operation, for it will be seen that as to those carriers which remain in position the springs 0 thereof will be extended as the frame J swings forward.- 'While this,'t0 a certain extent, adds to the load ino ratin .the 'machine,-it will be seenthat tiis loa comes" only upon a part of the carriers, that .is, upon such as are not moved at any one ad operation, and this is in part compen sated or by the fact that on the return movement the springs that have been extended or put under the extra stress, tend to swing the ame J the position to restore the other partsandpnt stress and counteract upon the springs 404. By thus maki' use of two sets o springs I am, therefore a le to secure the effect'on each of the raplr strips 404 of both springs without necessaril actually expanding orputting under additional stress the springs a which tend to hold the carriers and s 'ng frame or other operating device in juxtaposition, so thatI secure sufficient strength of's ring or, energy of spring action, to operate parts with the desired rapidity and that I secure this result without unloa the machine. It will further be seen, that y the use of a cans which acts positively to control the movement of the i to shift the carriers to positions type carriers to printing position, I revent any overthrow o the parts. It will e seen, therefore, that the brake devices heretofore required to prevent "overthrow or rebound may be dispensed with, or greatly reduced in energy, and the operation of the apparatus corres ondingly facilitated. I

Wit out limiting myself to the precise const etion and arrangement of parts shown, '1

1; The combination with thew camera of an adding machine, of springs connected to shift the t a device for 'fting the carriers to normal position and a second set of springs, arranged and connected to be put under tress tending to shift the type carriers when the said device is carried in a' direction from the latter.

2. The combination with the type carriers, and stops for defini the movements of the type carriers of an ad ing machine of springs 'rnited. by the stops, other springs for acting in the same direction, and means adjustable to put the latter springs under stress to aid in shifting the carriers.

3. The combination with the type carriers of an. adding machine, of two sets of springs to act .on, the said carriers to carry 'le in restoring the parts to normal. position it is 'only necessary to overcome the carriers to printing position,

them to printing position, one set normally under stress to effect said result, and means whereby the other set may be put under stress after the movement of the carriers begins.

4'. The combination with the type carriers one normal under constant stress to move of an adding machine, of two sets of springs,

said carriers, and means whereby when the machine is operated in adding the other sprin may be put under stress. A

"5. he combination with the type carriers of anadding machine, of spri to .carr' the carriers to printing position, means oreearrying the carriers to'norinal position, and springs connectin said means and carriers and arranged to e M under stress only as said means is carrier from the carriers. I

-- 6. Thecombination in an adding machine whereby the type carriers are shifted to positions determmed by said means, and 0t er springs, and means whereby the latter may be put under stress to supplementthe action of the first-named springs as the t ype carriers begin their movements in one direction.

by such s connected of the type carriers and means for defining the movements of such carriers, of springs t the position of said devices in respect to the carriers, substantially as set forth.

8. The combination with the type car; riers, and means for determining the niovements thereof in an adding machine, of spri for shifting the carriers to printing positions, a swinging frame, means for opcrating the frame to move the carriers to nor- .mal positions, and spring connections betwoe'n'the frame and carriers.

, 9'. The combination with the type carriers, and means for determining the movements thereof, of springs for shifting the carriers to printing positions,-a-swinging frame, means for operating the frame to move the carriers to normal positions, spring connections between the frame and carriers, and a cam for positively operating the frame.

10. T e combination with the type carriers, and means for determini the movements thereof, of a spring for s 'f-ting each carrier to rinting position, a reciprocating device for s rifting the carriers to normal positions, and a spri 1 connection between each carrier and said evice arr ed to be put under stress when the device is moved from the carrier.

11. The combination withthe type carriers, and the means for determining the movements thereof, and springs for carrying the type carriers to printing position, of a,

swinging frame and means for operating the same, and a spring connection between the frame and each carrier arranged to be put under stress as the frame leaves the carrier. ,12. The combination with the type',carriers, and means for determining the movements thereof and springs for carrying .the type carriers to printing position, of a swinging frame and a cam for operating the same, and a spring connection between the frame and each carrier arranged to be put under stresses the frame leaves the carrier.

13. The combination with the type earriers, sto s, nunierafkeys and springs for shifting t is carriers to printing position, of a swinging frame and: a cam arranged to act positively in both directions to swing the frame with and from the carriers, and a spring connection between said frame and each carrier.

14. The combination withtne t'pe carriers and swinging frame, of a cam or oper- -carriers to printing position, a shifter for shifting the carriers to non-printing position, and connections between the shifter and one set of springs whereby the latter are relaxed as the shifter is operated to set the carriers to non-printim position and which are put under stress w ten the shifter is moved from the carriers.

In testimony whereof I allix my signature in presence of two witnesses.
